    session-rdp: Add status flags for the graphics pipeline
    
    The graphics pipeline is a dynamic channel and has its own capability
    exchange.
    This means: If the connection is activated, then the graphics pipeline
    will not be ready yet.
    The RDP_PEER_PENDING_GFX_INIT flag signals, that there is a pending
    capability exchange (graphics pipeline not ready yet), while the
    RDP_PEER_PENDING_GFX_GRAPHICS_RESET flag signals, that
    gnome-remote-desktop needs to submit the monitor configuration and the
    size of the graphics output buffer to the client first, in order to be
    able to submit surface updates.
